Do I need a civil engineer for my property in Los Angeles or Orange County?
Yes. A civil engineer ensures your project complies with local grading, drainage, stormwater, and zoning regulations. In wildfire-prone areas, engineering services also help prevent post-fire erosion and flooding.
How do civil engineers help with wildfire recovery?
After a fire, civil engineers design erosion control plans, grading solutions, and stormwater systems to stabilize land, protect homes, and prevent mudslides. They also ensure rebuilding meets fire setback and safety codes. You can schedule a free consultation with our team to find the right services for your projects.
How does land surveying help after a fire?
Surveyors measure property boundaries, elevations, and changes to land caused by fires. This data supports FEMA flood certifications, construction staking, and grading plans needed to rebuild safely and meet insurance requirements.
Do you provide FEMA certifications in Los Angeles and Orange County?
Yes. We provide FEMA flood certifications and creek floodplain studies to determine risks, meet insurance guidelines, and secure approvals for rebuilding.
What is an ALTA survey and when is it required?
An ALTA/NSPS survey is a detailed land survey often required for commercial real estate transactions. It shows property boundaries, easements, rights-of-way, and improvements, protecting buyers, lenders, and developers from costly disputes.
How long does a land survey take?
Most surveys take a few days to a week, depending on property size and complexity. Larger subdivisions, hillside properties, or fire-affected land may require more time for accuracy.
What is construction staking and why is it important?
Construction staking places physical markers on your property to show exactly where buildings, roads, and utilities will be built. It ensures contractors follow engineering plans accurately, reducing costly mistakes.
Can you help with subdivision mapping in Orange County or Los Angeles County?
Yes. We prepare tentative maps and subdivision maps for residential and commercial projects, ensuring compliance with local zoning, infrastructure, and permitting requirements.
